Nice — here are reliable websites (and communities) that consistently surface off‑the‑beaten‑path, “hidden‑gem” adventures across Asia, with a short note on what each is best for and a source you can check right away:

• Atlas Obscura — the go‑to catalog of unusual, surprising and little‑known places (interactive maps and user submissions make it excellent for weird/unique finds). (atlasobscura.com)
• Lonely Planet — in‑depth destination guides and many “hidden gems / off the beaten track” features written by long‑time country specialists. Great for practical route and logistics tips. (lonelyplanet.com)
• Rough Guides — strong regional guides and curated lists for lesser‑visited towns, natural areas and road‑trip routes across Asia. (roughguides.com)
• Intrepid Travel — small‑group adventure operator that often launches new, locally focused trips to lesser‑visited villages, islands and trekking areas. Useful if you want guided, responsible access to remote spots. (intrepidtravel.com)
• G Adventures — similar to Intrepid: lots of small‑group, experience‑led itineraries that include off‑radar destinations and community stays. (gadventures.com)
• Nomadic Matt — budget / independent travel blog with practical tips and destination writeups that regularly highlight lesser‑known beaches, towns and routes in Asia. Good for low‑cost, independent options. (nomadicmatt.com)
• Culture Trip — local‑flavored stories and curated lists (city and regional pages often surface neighbourhood gems and local experiences). Also sells small group trips. (theculturetrip.com)
• Agoda (Special Editions / Hidden‑Gems features) — destination writeups focused on lesser‑visited spots in Southeast Asia; useful for finding quieter alternatives near popular hubs. (agoda.com)
• Airbnb Experiences — easy way to book local‑led “hidden‑gems” food, bike and micro‑tours hosted by residents (great for finding insider, small‑group activities). (airbnb.com)
• Condé Nast Traveler / CN Traveler — curated editorial lists that regularly publish “keep to yourself” beaches, towns and lesser‑known national parks across Asia. Useful for inspiration and photo‑tested ideas. (cntraveler.com)
• Reddit travel communities (e.g., r/AsiaTraveltips / r/TravelAsia) — crowdsourced, up‑to‑date recommendations from real travelers and locals; best for current on‑the‑ground tips and niche Q&A. (reddit.com)

Quick tips for using them together

• Start with Atlas Obscura or the editorial lists for inspiration, then check Lonely Planet / Rough Guides for logistics and seasonality. (atlasobscura.com)
• Use Intrepid/G Adventures or Airbnb Experiences to book vetted local guides when a hidden spot needs local access or permits. (intrepidtravel.com)
• Cross‑check community threads on Reddit and recent blog posts (Nomadic Matt, Culture Trip) for the latest road/entry updates and real traveler reports. (nomadicmatt.com)

If you want, I can: pick top hidden‑gem ideas for a specific country (Japan, Vietnam, Philippines, India, etc.), or build a short 7–10 day “off‑the‑beaten‑path” Asia itinerary using these sources. Which country or travel style are you thinking of?
